Default It's Time To Ask Another Question

O.K., many of the members know I I recently purchased the JessEm Dowelin Jig and really liked, stll do. Up until now I just played around with it and it works so very well.

Well, I'm finally in the middle of a real project in which I making the lid for a cedar chest. The lid is to be constructed out of five boards doweled edge to edge. I got the first three sets of holes drilled on three edges. I put the dowels in for a test of a dry fit, and all looked wonderful. I had spent quite a bit of time the day before getting the edges milled to a very nice tight fit.

With all that rederic said, here is the chestnut of the day, how much and where do you put the glue. I added glue and tried to put two of the workpieces together, of course the fit was terrible, I don't know where I thought that the glue would go, duh.

So, that's the question how much and where should I put the glue in order for it to not screw up the fit between the boards up?????

Hi Jerry. What type of dowels are you using? I've only used ones that are fluted, or have tiny grooves on them. This allows excess glue to exit the hole.

Brian,
Sounds like the same dowels that I'm using. My mistake, or think it was my mistake, is that I put glue on the edges of the boards as well as the dowel. I tried to not use but a small amount of glue, but it didn't work.

I got the boards apart, thank goodness I had only tired one joint, I'm still talking about wood working, not what that sounded like.

I let the glue set and then cleaned the edges up on the jointer and started over. This time I have only put glue on the dowels and not a lot of it. The fit looks alright so far. I had to hammer the workpieces to getter with a rubber mallet, hope that the seam still looks good after ithe glue sets up. I won't go any further until I see how the joint looks after the glue is set.

By the way, the boards being joined are 42" long, leaveing some lengh for trimming later, I'm putting 13 3/8" dowels into each joint, this might be over kill, I don't know so if it is and somebody with more experience knows, I'm open to suggestion.

I can drill about 30 holes before there is only one light of the three still lighting up on the PC cordless drill's fuel gauge. I change batteries when only the one light still lights up. I'm drilling into quarter sawed white oak, the wood is pretty hard. The batteries charge back up in less than 30 minutes, sure do like the cordless drill, it's my first one.

If learning about these things weren't so much fun I think that I have to give woodworking up, it seems that most of what I have done since I started this phase of my life is to learn and learn and no matter what I try there is more to learn, has anybody else found this to be true for them???

Jerry, I would think that you SHOULD be putting glue on the edges as well as the dowels. What I was always told was that the dowels were there for alignment purposes, not so much for joinery purposes. I was always told the glue joint (board edge to board edge) gave it the actual strength.

What was the actual problem you experienced? I assumed that it was a dowel issue... the glue trapped in the hold and not allowing the dowel to seat properly.

Brian,
The glue, as little as used of it, it would not let the the edges come together.

Bill just let me know his approach to the glue up and it is as Brian says that he does it which is of course to use glue on the edges. I am going to try it again and do my best to keep the glue at a minimum and clamp with a set of bar clamps and see what happens.

I'm thinking Brian may have hit on the real issue--the dowel holes need to be deep enough to allow a little glue at the bottom. When i use dowels, i usually drill about 1/8" deeper on each side. (for example--if the dowel is 2", i drill to 1 1/8" on each side) I've made the mistake of not drilling deep enough--more than once!! Using spiral grooved dowels like you did allows any excess glue to squeeze out, greatly reducing the chance that glue would keep a dowel from seating in the hole.

And yes, the edges of the wood need glue. (i've been there too!!)

Just did another attempt, the problem was that I had not clamped the first joint properly. I did a second attempt on the next seam in the lid and used bar clamps with lots of pressure, the fit looks fine, I'm happy.

Glad to hear it Jerry. I know how frustrating it can be when something doesn't go right.
